Q. I got following error when downloding PDF file. "TCPDF ERROR: Could not include font definition file: helvetica"

When "Safe fonts directory" option is enabled, there must be some bundled fonts in new font directory. Upload helvetica.php, helveticab.php, helveticabi.php, helveticai.php to new font directory at least. You can find these fonts in /YOUR PLUGIN DIRECTORY/post2pdf-converter/tcpdf/fonts directory.
